Cutting calories by 30% may be sufficient to shield the brain against aging

Cutting calories by 30% may be sufficient to shield the brain against aging

Science Alert reports: A calorie-restricted diet could slow down the aging that naturally happens in the brain as we get older, according to a new study of rhesus monkeys, and the findings could also be relevant to brain diseases such as Alzheimer’s. Researchers led by a team from Boston University analyzed the brains of 24 rhesus monkeys (Macaca mulatta) that had been fed calorie-restricted or standard diets for more than 20 years. After these lifelong dietary differences, the researchers found…

Eugenics: Child deaths projected to rise for first time this century, as aid cuts reverse decades of progress

Eugenics: Child deaths projected to rise for first time this century, as aid cuts reverse decades of progress

Sara Herschander writes: The world is a much better place than it used to be, especially for young children. Insecticide-treated mosquito nets and novel treatments have made malaria much less deadly for millions of kids. Many countries now have the tools and techniques they need to nurse even very premature babies back to health. And the stupendous rise of vaccines against deadly diseases — like measles, diphtheria, and pneumonia — have prevented countless children from getting sick to begin with….

Long-term calorie restriction in diet may slow biological aging in the brain

Long-term calorie restriction in diet may slow biological aging in the brain

PsyPost reports: A new study suggests that restricting calorie intake over a lifetime may slow the biological aging of support cells in the primate brain. The research provides evidence that a thirty percent reduction in calories preserves the metabolic function of cells responsible for insulating nerve fibers. These findings were published in the journal Aging Cell. The brain relies on complex networks of communication to function correctly. This communication depends heavily on white matter, which consists of nerve fibers coated…

Study reveals the age at which you hit the ‘tipping point’ into frailty

Study reveals the age at which you hit the ‘tipping point’ into frailty

Science Alert reports: The bumpy trajectory of human aging may have a tipping point as we enter our twilight years, a new study has found. Past the age of around 75, our bodies can no longer easily recover from injury or illness – a sharp decline in resilience that comes with a corresponding rise in the risk of dying, according to researchers at Dalhousie University in Canada. Their model looks at aging as a balance between damage and repair, with…

‘The precedent is Flint’: How Oregon’s data center boom is supercharging a water crisis

‘The precedent is Flint’: How Oregon’s data center boom is supercharging a water crisis

Rolling Stone reports: In the spring of 2022, Jim Doherty kept having the same conversation with folks at the only grocery store in Boardman, his eastern Oregon hometown, or at the grain depot where he picked up food for his four ranch dogs. Healthy adults that these people knew were coming down with unexplained medical conditions, including diseases and cancers that usually afflicted the elderly. “It was kinda grim,” Doherty says. Sixty years old, broad-chested, with a salt-and-pepper goatee, Doherty…

We can’t diet and exercise our way out of the next pandemic

We can’t diet and exercise our way out of the next pandemic

David Wallace-Wells writes: In the event of a sudden pandemic, what should we do? This month, Jay Bhattacharya, the director of the National Institutes of Health, offered a remarkably blunt answer: nothing. It’s been nearly six years now since the United States’ first reported cases of Covid-19, and the country is in a merciful lull when it comes to pandemic recriminations, as Robert F. Kennedy Jr.’s ongoing war on vaccine confidence now dominates the public health culture wars. But Bhattacharya,…

By Kavitha Surana and Lizzie Presser This story was originally published by ProPublica Tierra Walker had reached her limit. In the weeks since she’d learned she was pregnant, the 37-year-old dental assistant had been wracked by unexplained seizures and mostly confined to a hospital cot. With soaring blood pressure and diabetes, she knew she was at high risk of developing preeclampsia, a pregnancy complication that could end her life.  Her mind was made up on the morning of Oct. 14,…

How the shutdown of USAID has already killed hundreds of thousands of people

How the shutdown of USAID has already killed hundreds of thousands of people

  Atul Gawande writes: It was January, my final week in the outgoing Administration. In a few days, Donald Trump would be inaugurated as President. I had come to the United States Agency for International Development in early 2022, leaving my surgery practice and public-health research in Boston to lead the agency’s global-health efforts. Now I’d be returning to my previous life. I spent my last days at U.S.A.I.D. in meetings with our civil- and foreign-service leaders, thanking them. Their…

The evolving science of dietary restriction

The evolving science of dietary restriction

Andrew Steele writes: The idea that eating less might make us live longer has been around for thousands of years. Even Hippocrates, the Ancient Greek physician, argued that, “When a patient is fed too richly, the disease is fed as well. Any excess is against nature.” Scientists have now spent decades testing whether his advice holds true. The first striking evidence came in the 1930s, when American nutritionist Dr Clive McCay found that rats fed a restricted diet lived almost…

‘Access to good food should be a universal right’

Hannah Goldfield writes: One morning in late September, the writer and former Times columnist Mark Bittman walked into the Lower East Side Girls Club, a rec center in Alphabet City and the site of what would become, in less than eight hours, his first restaurant. At 6 P.M., an inaugural group of guests would arrive for the soft opening of Community Kitchen, a not-for-profit fine-dining experiment that Bittman spent years concocting, and which had found a home—for the next few…

Public health professor warns the Trump’s ‘eugenics’ policy echoes Nazism

The Daily Beast reports: An eminent ER doctor and health policy expert has warned that President Donald Trump’s government shutdown talk about “deserving” patients mirrors a “eugenics” policy adopted by the Nazis. The shutdown is about to enter its fourth week after Congress failed to pass full-year funding. The White House and Speaker Mike Johnson are demanding spending cuts and immigration concessions, while Senate Democrats insist on extending ACA subsidies and undoing the summer healthcare cuts before reopening agencies. Dr….

Only 1% of people are eating a healthy and sustainable diet, major report finds

Only 1% of people are eating a healthy and sustainable diet, major report finds

BBC Science Focus reports: A major report on the global food system has found that less than 1 per cent of the world is eating a diet that’s good for the planet and human health. But switching to a healthier eating pattern could prevent up to 15 million premature deaths per year, while cutting global greenhouse gas emissions by up to 20 per cent. These are the findings of a report by the 2025 EAT-Lancet Commission. The report brings together…

White House senses political risk on healthcare despite Trump’s shutdown bravado

The Wall Street Journal reports: President Trump has projected unwavering confidence that he is winning the messaging war over the government shutdown. But behind the scenes, his team is increasingly concerned that the issue at the center of the debate will create political vulnerabilities for Republicans. Advisers are worried that the GOP will take the blame for allowing healthcare subsidies to expire, raising costs for millions of Americans ahead of next year’s midterm elections, according to administration officials. Inside the…

Mediterranean diet may mitigate inherited risk of Alzheimer’s disease

Mediterranean diet may mitigate inherited risk of Alzheimer’s disease

PsyPost reports: A new study has revealed that a person’s genetic makeup can alter how small molecules in their blood, known as metabolites, are linked to their risk of developing dementia. The research, published in Nature Medicine, also suggests that following a Mediterranean diet may be particularly effective at lowering dementia risk for individuals who carry the highest genetic predisposition for Alzheimer’s disease. Alzheimer’s disease is a neurodegenerative condition that causes a progressive decline in memory and other cognitive abilities….

Trump’s most lethal policy: ‘People are dying every day and night’

Trump’s most lethal policy: ‘People are dying every day and night’

Nicholas Kristof writes: The Trump administration has claimed that no one has died because of its cuts to humanitarian aid, and it is now trying to cancel an additional $4.9 billion in aid that Congress already approved. Yet what I find here in desperate villages in southwestern Uganda is that not only are aid cuts killing children every day, but that the death toll is accelerating. Stockpiles of food and medicine are running out here. Village health workers who used…

Kaitlyn Tiffany and Matteo Wong write: On Tuesday afternoon, three parents sat in a row before the Senate Judiciary Subcommittee on Crime and Counterterrorism. Two of them had each recently lost a child to suicide; the third has a teenage son who, after cutting his arm in front of her and biting her, is undergoing residential treatment. All three blame generative AI for what has happened to their children. They had come to testify on what appears to be an…
